So just to be clear about your situation:
- you installed 11.10 to your computer?
- it boots up fine and works?
- you tried 10.04 and 12.04 and neither boot?
- you intend to install 12.04?

What graphics card are you using?

I would first attempt to set nomodeset in the grub kernel parameters and see if that avoids the blank screen:

11.10 gave me problems too. I suggest installing 12.04 over your previous installations of Ubuntu, but don't install it over Windows 7. I was able to do this with the USB installation.

It managed to install within 10 minutes or so, and I previously had the same kind of problem you did. I was using a version of 10, and it just wouldn't upgrade to 11.10 properly.

I had the same problem when I first installed 11.10. It is a graphics issue. Hold down shift to get to the grub. I found the info needed in this thread http://ubuntuforums.org/showthread.php?t=1741887 . Hopefullly it will be the same for you. If not do a search for your graphics card, and you should be able to find some help
